Question

select the correct answer.
why are kelp and seagrass not found in deep oceanic water?
○ a. there are no nutrients available in deep water.
○ b. theres no availability of sunlight.
○ c. deep waters are full of grazing herbivores.
○ d. deep water currents are too strong.
○ e. the deep sea floor cannot anchor these species.

Explanation:

Kelp and seagrass are photosynthetic organisms. They need sunlight for photosynthesis. In deep oceanic water, sunlight cannot penetrate sufficiently. Without sunlight, they cannot carry out photosynthesis to survive and grow. Options A is incorrect as deep water has nutrients. Option C is wrong as grazing herbivores presence is not the main reason. Option D is incorrect as strong currents are not the key factor. Option E is wrong as they can be anchored in shallow areas (where they are found) and the issue is not about anchoring in deep sea floor mainly but lack of sunlight.

Answer:

B. There’s no availability of sunlight.
